[news.eclipse.platform.swt] Draw2D PolylineConnection

[ben00ze@xxxxxxxxx (benjamin)]

I posted this thrad on eclipse.platform newsgroup, but maybe swt newsgroup 
is a better choice .... 




Hi all,

I have a question about PolyLineConnection


I made a class named SystemeFigure in which I can added some kind of 
Rectangle.
In the class named SystemeFigure, I added a MouseMotion listener which 
allow me to move the RectangleSysteme selected and this works well.
But I also tried to add a PolyLineConnection when a button is enabled.

public class SystemeFigure extends Figure {
.....

  new MouseMotionListener()    {
     .....
     public void mouseDragged(MouseEvent me)       {
         if ( me.getSource() instanceof RectangleSysteme){       
((RectangleSysteme)me.getSource()).setLocation(me.getLocation());
         }
      }

  }


  new MouseListener() {
public void mousePressed(MouseEvent me)         {
          PolylineConnection c = new PolylineConnection();
          ChopboxAnchor sourceAnchor = new ChopboxAnchor(source);
  ChopboxAnchor targetAnchor = new       
ChopboxAnchor(((RectangleSysteme)me.getSource()));
           c.setSourceAnchor(sourceAnchor);
c.setTargetAnchor(targetAnchor);
add(c);
}

}




private class RectangleSysteme extends RectangleFigure
{
.....

 public void setLocation(Point p)
{
   super.setLocation(p);
   .... // some stuff to do
}
}




But when I add the PolyLineConnection, my RectangleSysteme go to their 
first position, and it's impossible to move them again.

Someone can help me please ?


ps : sorry for my english
